Executive Summary

ANALYST: COI RESEARCH

The institution migrated core credit card transaction switching from proprietary mainframes to commodity x86 hardware running open-source Linux.

rate_review Analyst Verdict

"A rare but highly effective architectural pivot. Moving away from the 'mainframe tax' (MIPS costs) to open-source software on commodity hardware delivers massive long-term TCO savings, though it requires significant internal engineering talent."

warning The Challenge

The cost of processing millions of credit card transactions on proprietary mainframe hardware was rising annually due to licensing fees and hardware lock-in. The rigid mainframe environment also slowed down the deployment of new software features compared to modern distributed systems.

psychology The Solution

The organization re-engineered its core transaction authorization engine to run on Red Hat Enterprise Linux (RHEL) using containerized microservices on commodity hardware. This architecture allows them to scale processing power horizontally at a fraction of the cost of vertical mainframe scaling.
